Application flled .Tune K1,

This invention relates tocar roofs, and particularly to car roofs of the steel seltsustaining type, formed of roof sheets which extend from eaves to eaves'and are lapped and connected together at their sid-e marginal portions. i p

The objects of the inventionare to construct the lapped marginal portions of contiguous rootl sheets, so as to impart great strength to the roof as a whole, to prevent leakage between the contiguous roof sheets, and to provide an additional rigidifying means interposed between the lapped marginal portions ot' the roof sheets.

In addition to the general objects recited above., the invention includes among its objects such ot-her improvements andadvantages in construction and operation as are found to contain in the structures or devices hereinafter described or claimed.

comprises side plates 11 and end plates 1Q which are respectively supported in any preferred manner by the sides and ends of a railway car.

In accordance with the present invention. the car root is constructed of root sheets 13; of arched form from eaves to eaves of the roof. These root' sheets are preferably con-- structed of sheet metal and are formed at then1 eaves ends with laterally-extended flanges 14 merging at their outer edges into depending flanges 15. Vhen assembled on the roof, the laterally-extended flanges 14 overlie the top faces of the side plates and the depending flanges 15 engage Athe outer side faces of the side plates 11 and function as eaves llashing strips. The transverse marginal portions of vcontiguous root sheets arelapped troml eaves to eaves of the root', and said transverse marginal portions are respectively torm'ed with transverse corrugations 16 and 17, Vextended between the lateral flanges 14 at the eaves endsot the roof` sheets and both upstanding from their respective roof sheets. As shown more particularly in Figures 3 and et the lapped marginal portions of a pair of contiguous roo'l sheets 13 are extended transverselyof their corrugations'l and 17 beyond said corrugations, as shown at 18418, thereby providinga joint, which effec-tively prevents water from getting in between the lapped corrugations.

The overlapping corrugation 16 of the overlapping marginal portion is formed with an upstanding rib 19 projecting from the apex of said corrugation 16 and extending from eaves to eaves end ot itsroot sheet and merging into the eaves flange `14- at the opposite eaves ends of the roof sheets, as Vshown more particularly in Figure 9. On the other hand the underlapping corrugation 17 of the underlapping portion of the other roofsheet is formed with aI depending rib 20, projected downwardly fromY the apeii of said corrugation 17 and ext-ended transverselyfrom eaves to eaves end of the root' sheet, but terminating at the inner edges ci the flangesle at the eaves ends of the root' sheet. f Thesev reverselyv-extended compan- 9a transverse ribs i9 and 2;@ serv@ t0 greatly vstrengthen the lapped transverse marginal portions of contiguous rooi1 sheets, and the metal and forms with the companion ribs,

19 and 2O and the companion ecirugations 16 and 17 of a pair of contiguous roof sheets, a substantially solid carline of y strength. yAs shown in Figure 5, *theV filler -strip 21 lterminates 'within ythel cares ends y of the roof. rootl i'orined in the rmanner `above described is substantially water-.tight throughout and although of very simple construction, since it may be lorined en-V tirely of sheet metal roof' sheets shaped by l dies, is nevertheless of great strength Vand vfpossesses. a'high degree of rigidity for resist-ing stresses, inasmuch as it embodies in its construction :practically solid carlines disposed at frequent intervals along the roof. LThe roof ina-y be constructed of a plurality of roof sheets of like formation, of

the type shown in Figuiei). Each roof sheetV is formed at its eaves ends with the transversely-extended flanges 14 merging at their z outeredges intov the de ending Ytlangesrl. ,One transverse marginal, portion of a roof sheet is provided with the corrugation 16 having the upstanding rib 19 adapted to overlap the transversemarginal portion of a` contiguous roof sheet, vvhereasthe other ftransversemarginal port-ion ofthe roof sheet is formed Awith Vthe coirugation l17 having 'they depending vrib, 2O adaptedto underl'ap` I e opposite-contiguous rooiffsheet,
